RM v2.174 and Kemper OS 188.8.131.5219 Release are communicating now .
I uninstalled RM , restarted PC ,installed RM, plugged Kemper ( WIN7 recognized and installed drivers).
If I unplug the Kemper then the driver info disappears from the Sound/video controllers page. It reappears if I reconnect so I removed the driver here.
While Kemper is plugged in, try right-click on Kemper Profiler in Device manager and then on Uninstall driver. After that unplug and plug in Kemper again, Just a thought, maybe that will help.
But first try exactly what I did, I worked for me.
